Abstract

Embodiments of the disclosure relate generally to illumination synchronization in a multi-imager environment. Embodiments include systems, methods, computer program products, and apparatuses configured for operating a near-field illumination source associated with a near-field image sensor, based on a first illumination pulse train. An exposure period of a far-field image sensor is determined and one or more characteristics of the first illumination pulse train are modified to accommodate the exposure period of the far-field image sensor.
